It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, which spans finance, analytics, AI/ML, and utility categories. The endpoint accepts POST requests and returns JSON.\n\nPricing is $0.02 per request (20,000 base units of USDC on the Base network, where USDC has 6 decimals). Payment is handled inline via the x402 protocol — no API keys, accounts, or rate limits are required. The payment settles on the Base L2 using the \"exact\" scheme, paying to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.\n\nDocumentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The specific fields returned in the JPM quote (e.g., price, volume, timestamp) are unknown and must be inferred from the endpoint path and the broader \"Finance & Web3\" category listing on the homepage. The endpoint is confirmed live via a 402 challenge response.","tags":[],"capabilities":["stock-quote","market-data","x402-payment","usdc-base","pay-per-call","no-api-key","json-response"],"categories":["finance","market-data"],"synonyms":["JPM stock quote","JPMorgan Chase quote","stock price API","equity quote","market quote API","x402 finance","micropayment stock data"],"warnings":["No documentation available — /docs, /api, /pricing, and /README pages all show only 'Connect wallet' with no content.","No OpenAPI or schema definition; request body and response structure are completely unknown.","The specific data fields in the JPM quote response cannot be verified.","Provider site offers many diverse endpoints (AI, analytics, finance, utilities) all at $0.02 — unclear whether all are fully implemented or stubs."],"endpointUrl":"https://lowpaymentfee.com/api/v1/market/quote/JPM","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/market/quote/JPM","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base).
